The endoplasmic reticulum (ER) and mitochondria are essential organelles that play crucial roles in maintaining cellular homeostasis. The simultaneous induction of ER stress and mitochondrial dysfunction represents a promising yet challenging strategy for cancer treatment. Herein, a hollow calcium-copper bimetallic nanoplatform is developed as a cascade amplifier to reinforce ER stress and mitochondrial dysfunction for breast cancer treatment.

Correlation between echocardiographic and pathoanatomic variables and their prognostic value in murine cardiomyopathy models remain unknown. Using echocardiography, morphometrics, and survival monitoring, we characterized transgenic (TG) mice with dilated cardiomyopathy due to cardiac overexpression of β-adrenoceptors focusing on predicting heart failure (HF) risk and HF mortality. In 12-month-old non-TG and TG mice, echocardiography was performed to determine left ventricular (LV) dimensions (d), wall thickness (h), and fractional shortening (FS).

Introduction: Knee osteoarthritis (KOA) is a chronic degenerative bone metabolic disease that primarily affects older adults, leading to chronic pain and disability that affect patients' daily activities. Electroacupuncture (EA) is a commonly used method for the treatment of chronic pain in clinical practice. Previous studies indicate that the endocannabinoid system is involved in EA analgesia, but whether endocannabinopeptide VD-hemopressin (α) and RVD-hemopressin (α) derived from hemoglobin chains are involved in EA analgesia is unclear.

Background: Since the outbreak of the Coronavirus Disease 2019 (COVID-19), front-line nurses have faced not only daily work stress but also a high risk of infection and excessive workload, leading to unsatisfactory professional quality of life (ProQOL). This study aimed to explore whether self-compassion (SC) and benefit finding (BF) play a chain mediating role between work stress and ProQOL among Chinese nurses during the COVID-19 pandemic.

Methods: From March to April 2022, a sample of 13,936 Chinese nurses was recruited through snowball sampling.

Geographically weighted accelerated failure time model for spatial survival data: application to ovarian cancer survival data in New Jersey.

BMC Med Res Methodol

October 2024

Department of Epidemiology and Biostatistics, School of Public Health, Xi'an Jiaotong University Health Science Center, No. 76, Yanta Xilu Road, Xi'an, Shaanxi, 710061, China.

Background: In large multiregional cohort studies, survival data is often collected at small geographical levels (such as counties) and aggregated at larger levels, leading to correlated patterns that are associated with location. Traditional studies typically analyze such data globally or locally by region, often neglecting the spatial information inherent in the data, which can introduce bias in effect estimates and potentially reduce statistical power.

Method: We propose a Geographically Weighted Accelerated Failure Time Model for spatial survival data to investigate spatial heterogeneity.

Article Synopsis
  • Non-optimal temperature significantly contributes to global disease burden, but most studies have focused on outdoor temperatures, potentially leading to misclassification of personal temperature exposure.
  • The CKB-Air study analyzed temperature data from 477 participants across personal, household, and outdoor settings during summer and winter in China, recording around 88,000 person-hours of data.
  • The study found strong correlations between personal and household temperatures in winter and significant predictors for personal temperature exposure, achieving good prediction accuracy, while identifying a U-shaped relationship between personal temperature exposure and heart rate.

BAFF overexpression in triple-negative breast cancer promotes tumor growth by inducing IL-10-secreting regulatory B cells that suppress anti-tumor T cell responses.

Breast Cancer Res Treat

October 2024

Department of Pathogenic Microbiology and Immunology, School of Basic Medical Sciences, Xi'an Jiaotong University Health Science Center, Xi'an, 710061, 76 West Yanta Road, China.

Purpose: Despite BAFF's (B cell activating factor, BAFF) known influence on B cell survival and proliferation, its specific effects within the tumor microenvironment remain unclear. We aimed to elucidate how BAFF overexpression in breast cancer cells impacts tumor growth and the functions of T and B cells in the tumor microenvironment.

Methods: BAFF was overexpressed in the 4T1 mouse triple-negative breast cancer cell line, and tumor growth, immune cell infiltration, and activity were assessed in vitro and in vivo using flow cytometry, co-culture assays, and mouse tumor models with B cell depletion.

Aim: Compared with the C57BL/6N substrain, the C57BL/6J substrain is more susceptible to the angiotensin II (Ang II)-induced development of dissected abdominal aortic aneurysms (AAAs). The aim of this study was to elucidate whether the widely used C57BL/6N mouse substrain is as susceptible as the C57BL/6J mouse substrain to porcine pancreatic elastase (PPE) infusion-induced experimental nondissected AAA development.

Methods: Experimental nondissected AAAs were induced in C57BL/6J and C57BL/6N mice via transient aortic luminal infusion of PPE.

Histone deacetylases (HDACs) play critical roles in cardiovascular diseases (CVDs). In addition, reactive oxygen species (ROS) produced by NADPH oxidases (NOXs) exert damaging effects due to oxidative stress on heart and blood vessels. Although NOX-dependent ROS production is implicated in pathogenesis, the relationship between HDACs and NOXs in CVDs remains to be elucidated.

Pharmacol Rep

February 2025

Department of Biochemistry and Molecular Biology, School of Basic Medical Sciences, Xi'an Jiaotong University Health Science Center, 76 Yanta West Road, Xi'an, Shaanxi, 710061, China.

Fibrosis, characterized by excess accumulation of extracellular matrix components, disrupts normal tissue structure and causes organ dysfunction. Long noncoding RNAs (lncRNAs) are a subset of RNAs longer than 200 nucleotides that are not converted into proteins. The increasing research indicated that lncRNA maternally expressed gene 3 (MEG3) was dysregulated in the pathologic process of fibrosis in several tissues.

Inflammation is a protective response to pathogens and injury. To be effective it needs to be resolved by endogenous mechanisms in order to avoid prolonged and excessive inflammation, which can become chronic. Specialized pro-resolving mediators (SPMs) are a group of lipids derived from omega-3 fatty acids, which can induce the resolution of inflammation.

Electronic address:

Cellular senescence (CS) is characterized by the irreversible cell cycle arrest and plays a key role in aging and diseases, such as cancer. Recent years have witnessed the burgeoning exploration of the intricate relationship between CS and cancer, with CS recognized as either a suppressing or promoting factor and officially acknowledged as one of the 14 cancer hallmarks. However, a comprehensive characterization remains absent from elucidating the divergences of this relationship across different cancer types and its involvement in the multi-facets of tumor development.

Article Synopsis
  • Scientists studied how methamphetamine (METH) affects memory in mice and found it messes with their learning abilities.
  • They created models to see how METH changes brain cells and discovered that METH causes inflammation in the brain early on, but this doesn’t get worse with more doses.
  • The researchers believe that even though the inflammation might not get worse, certain molecules linked to it stick around and are connected to the mice’s bad behavior, suggesting that treating inflammation could help with problems caused by METH.

Ambient Air Pollution and Hospitalizations for Schizophrenia in China.

JAMA Netw Open

October 2024

Department of Occupational and Environmental Health, School of Public Health, Xi'an Jiaotong University Health Science Center, Xi'an, Shaanxi, China.

Importance: Schizophrenia episodes may be triggered by short-term environmental stimuli. Short-term increases in ambient air pollution levels may elevate the risk of schizophrenia episodes, yet few epidemiologic studies have examined this association.

Objective: To investigate whether short-term increases in air pollution levels are associated with an additional risk of schizophrenia episodes, independent of absolute air pollution concentrations, and whether sustained increases in air pollution levels for several days are associated with more pronounced risks of schizophrenia episodes.
